Noise

Construction equipment, loud vehicles, amplified music, air conditioners, and loud parties are all examples of noise found in urban areas. Understandably, certain noise levels must be tolerated by all citizens in order for normal functions of urban life to continue. However, excessive, unnecessary, and/or annoying noise is regulated.

Amplified Noise at Special Events

Public Event

It’s important to review the noise ordinance to know all of the specific requirements for amplified noise at special events. However, the key points are that the maximum decibel limit at the perimeter of the event is 100dBA between the hours of 9 am and 9 pm (the Environmental Health Department has a noise meter you may borrow). Don’t forget to give the neighbors advance notice!

Private Event

(not requiring a Special Event Permit, located at a park, business, or nonprofit facility; and to which the general public is not invited)

It’s important to review the noise ordinance to know all of the specific requirements for amplified noise at special events. However, the key points are that the maximum decibel limit at the perimeter of the private special event is 80dBA between the hours of 9 am and 8 pm (the Environmental Health Department has a noise meter you may borrow). After 8 pm regular noise ordinance levels apply. Don’t forget to give the neighbors advance notice!

If you are concerned about the level of noise at home or work, the Environmental Health Department has a noise meter that you may borrow to check the noise level at your property line. Talking to your neighbor before making an official complaint will often deliver the best results. If communication fails, contact the Aspen Environmental Health Department or Aspen Police Department. Both departments have access to noise meters and will be able to take readings at your property line to determine if the noise in question is within allowable limits for the zone district, and if necessary, contact the neighbor.
